Since CoreImage is not part of AppKit, a fix to CoreImage wouldn't
necessarily change the AppKit version number.
To clarify: I'll check if(floor(NSAppKitVersionNumber >
NSAppKitVersionNumber10_4)) to determine if I'm running on Leopard or
Tiger, since I don't think it's likely that Apple will change
CoreImage to only reverse gradients when linking on 10.5.
Right now, I'm probably going to use Gestalt() to determine whether
or not my method should flip the CIVectors unless anyone has a
better idea.
There was an exceedingly long discussion on the merits of Gestalt()
vs. other version checking methods on macosx-dev a week or so ago.
It's archived, so hopefully that doesn't start up again here :).
